Send us Fan Mail How Recursive Optimization, Generative Design, and Cybersecurity Risks Are Shaping the Next Wave of AI Systems Key Takeaways: 🔄…
The architecture is the entire reason this succeeded.
WCO essentially built a system with two AIs working in a rigid tandem.
A boss and a worker, right?
Exactly.
They created a boss model and a worker model.
The boss was WCO's hand-built AI, which they called AID, and it was running on Cloud Opus 4.7.
Which is a heavy hitter.
Oh, absolutely.
And its sole job in this environment was evaluation.
It just observes how the worker is processing tasks.
It rewrites the instructions for how the worker thinks, tests the new version, and only keeps it if it actually beats the previous one.
Right.
Demonstrably beats it.
I want to focus on the worker model for a second, though, because this is where the resource allocation gets really fascinating.
The worker choice is key here.
The worker was not running on a massive flagship model like Opus.
And looking at the data, the choice to use a lightweight model wasn't an accident.
They were operating on a strictly fixed compute budget.
Which fundamentally changes the experiment, honestly.
When you are on a fixed budget, your cost per token is like your most important metric.
Exactly.
By using the cheaper model as the worker, the system could afford exponentially more attempts, you know?
More iterations, more trial and error runs for the exact same amount of money.
